Huawei S1720-28GFR-4P-AC Switch – Product Datasheet

Name: Huawei S1720-28GFR-4P-AC Switch - SunSpike
SKU: S1720-28GFR-4P-AC

Product Overview

The Huawei S1720-28GFR-4P-AC is a next-generation, energy‑efficient gigabit Ethernet switch designed for enterprise access layer deployments. Developed by Huawei, this fully‑managed switch offers 24×10/100/1000BASE‑T electrical ports and 4×1000BASE‑X SFP optical uplink ports, delivering wire‑speed Layer 2 switching performance.

The S1720‑28GFR‑4P‑AC belongs to the Huawei S1700 series, which provides multi‑service access capabilities, excellent extensibility, Quality of Service (QoS) guarantees, powerful multicast replication, and carrier‑class security. It is ideal for small to medium‑sized businesses, Internet cafes, hotels, schools, and corporate network environments requiring stable, high‑speed LAN connectivity.

Key advantages include:

Plug‑and‑play simplicity – no complex configuration required; connect power and network cables for immediate operation
Fan‑free natural heat dissipation – silent operation suitable for noise‑sensitive environments
Web‑based management – intuitive GUI for easy switch administration
Comprehensive security – hardware ACL, port‑based MAC filtering, 802.1X authentication, RADIUS support, and system self‑defense against various attacks
Intelligent upgrade – one‑click automated version upgrades via Huawei Online Upgrade Platform (HOUP)
